- • From ta = -25 s until to = -15 s the plane is taxiing east along the runway at a constant speed of 4 m/s. From ts until te = -10 s the plane slows down at a constant rate and comes to rest. • From te until to =0 the plane turns around, turning nearly in place so that by to it is facing west. • At to = 0 the plane is near the east end of the runway, at rest. From to until ti = 5.0 s it speeds up with a constant acceleration going west. At t, it is going at a speed of 8.75 m/s. • After t, the plane continues speeding up, but at a steadily reducing rate (i.e. it is still speeding up, but the magnitude of its acceleration is decreasing). It lifts off at t2 = 65 s going at a speed of 85 m/s, having gone a distance of 2980 m down the runway. • From t2 until t3 = 240 s the plane is climbing at an angle of 5.0° above horizontal, speeding up at a constant rate. At t3 it is going at a speed of 230 m/s. • At t3 the plane levels off, so it is flying at a constant height.
